li atented Jan. 6, 1931 PATENT @FFEQE LE ROY Assam, or MILFORD, connncrronr AUTOMOBILE VENTILA'IOR A Application filed January 31, 1929. Serial'No. 336,586.

My invention relates to new and useful improvements in ventilators, and has particular relation to a ventilator adapted for use with a closed vehicle as a closed automoblle. 5 An object of my invention is to provide a means for removing impure air and gaseous fumes from the interior of a closed car, by drawing or sucking the same from the mterior of the car during movement of the latter.

A .further object of my invention is to provide a means for the purpose indicated, which normally does not provide a passage between the interior and exterior of the car but which automatically operates to provide such passage when the car is in motion.

An additional object of the invention is to provide a ventilator as indicated which when in place is substantially out of sight and which will not in any way detract from the appearance of the car and which will be out of the way andnot interfere withthe normal use of the car. I

In the accompanying drawing I have shown a satisfactory embodiment of the invention but it is to be" understood that the drawing and'the following description are,

by way of illustration only and since changes in construction, combination and arrangement of parts will readily suggest themselves reference must be had to the appended claims for a definition of the limitations of the invention.

In the drawing:

, Fig. 1 is a vertical sectional view showing the arrangement of valves or checks; and

ljig. 2 is a sectional view on the line 22 of Fig. 1 with the register omitted.

' Referring in detail'to the drawing, at 5 is shown a portion of an automobile body, preferably a floor board, the same being provided with an opening 6 within which extends a vertically disposed throat or neck portion 7 of my ventilator. The upper end of the throat 7 fits snugly within the opening 6 and is secured to a register 8 arranged in the floor 5 of the automobile to cover the opening 6. Register 8 is of any preferred construction and includes a slide adapted to ment within certain limitations.

"reaches the dotted line he opened and closed to establish and cut ofi scribed to automatically open the register at the proper time.

Communicating with the lower end of the throat member 7 is a horizontally arranged tube 10 of substantially the same inside dimensions as the throat. With throat 7 this member 10 provides a substantially inverted T-shaped passage. Itis assumed that the vehicle to which my ventilator is attached is traveling toward the right in Fig. 1, and the front end of the tube 10 forming the hore5 izontal' passage is provided with a funnelshaped or flared portion 11 to direct air into the member 10 as the automobile moves along the road.

At its rear end, horizontal member 10 is closed by a pivoted damper or flap valve 12, the same being freely pivoted 'or hinged at 13 and adapted to move to open position as shown by the dotted lines. Arranged within the throat 7 is 'a valve or check 14, pivoted intermediate its ends as at 15 for free moves The full line position of valve 14 in Fig. 1 shows the valve closing the throat 7 and in this view it will be noted that the valve 14-. is engaging so the depending finger 9 of the register slide; It will be apparent from the foregoing that my ventilator is disposed below the floor of the automobile. Assuming the parts to be in the relative positions shown in full s5 I lines, and the register 8 closed, as the car moves forward air will enter the funnel 11. A baffle plate 16 in passage 10 deflects the air downwardly to prevent it rising in the throat 7 The pressure of air against valve 12 forces it open, and a wire 17 connecting valves 12 and 14 causes valve 14. to assume the dotted line position shown when valve 12 position in which it is shown.

Wire 17 i's loosely connected to the valves .12 and 14 by the buttons 18 whereby there is a slight free movement to allow for the difi'erent positions of the valves relative to the wire; Qwmg to the contact between the up .104

at'the juncture of the up er wall of said cross per end of valve 14 and the depending finger 9 of the register slide, the register is opened as the valve 12 moves to open position.

The passage from the interior of the car through the throat 7 and member 10 now beneath the floor of-the car is concealed and completely out of the way.

Having thus described my invention what I claim is:

1. In a ventilator, a vertical throat portion, a horizontal cross pipe communicating with the lower end of said throat portion to provide an inverted T-shaped passage, a funnel shaped intake on the forward end of said cross member, a flap valve enclosing the rear end of thehorizontal passage; and a bafile member and one wall 0 the throat portion, said baflie being inclining downwardly and away from said funnel to deflect the air against the free end of the flap valve;

2. Ina ventilator, a throat portion, a cross member communicating with said throat portion, a flap valve closing one end of said cross member, a valve closing the passage through the throat member, said flap valve adaptedto be opened by air passing through said cross member, and means connecting said valves whereby on said flap valve being opened the valve in the throat portion will be opened. v

3. In a ventilator, a throat portion, a cross member communicating with said throat portion, at one of the ends of the latter, a flap valve closing one end of said cross member, a pivotally mounted valve closing the passage through said throat portion, a register closing the end of said throat portion remote from the crossmember, said flap valve adapt- 4 ed to be 0 ened by air passing through said cross mem er, means connecting said valves whereby on said flap valve being opened said pivoted valve is pulled open, and means whereby as said pivoted valve opens it opens the register. I 1

4. In combination with a floor board hav ing an opening therein, a ventilator having a throat portion projecting into said 'opening, a register over" said opening, a valvewithin said throat portion and adapted when moved to open position to open said register a cross member communicating with sai throat portion, and means within said cross member and adapted to be influenced by the passage of air through'the member to open the valve in the throat portion,

5. In a ventilator, a member having two passages, a valve in one of said passages ada ted to be opened by air passing through sai passage and to close when the air stops passing, a valve pivoted in the other of said passages, means whereby as the first valve opens and closes the second valve does likewise, a-register in the-passage containing the second mentioned valve, said register adapted to be moved to open position by the second mentioned valve as'it moves to open position.
